Determination of NLRP3 (rs4612666) and IL-1B (rs1143634) genetic polymorphisms in periodontally diseased and healthy subjects.

Objective: The focus of the current study was to identify if a possible association between NLRP3 (rs4612666) and IL-1B (rs1143634) single-nucleotide polymorphisms (SNPs) may be implicated in the etiopathogenesis of chronic periodontitis (CP) in a Colombian population.

Design: One hundred and twenty-four CP subjects and 81 periodontally healthy controls (HC) were recruited. Periodontal status was assessed by criteria based on probing depth, clinical attachment level, extent, and severity of periodontal breakdown.
